Interviews in which a subject
or group of subjects talk while
working on a mathematical
task or set of tasks.
ORIGIN
Task-based interviews have
their origin in clinical interviews
that date back to the time of
Piaget, who is credited with
pioneering the clinical interview.
USED
Was used in order to gain a deeper
understanding of children’s
cognitive development
USED
By researchers in qualitative
research in mathematics
education to gain knowledge
about an individual or group
of students
FOR ASSESSMENT
Have been useful in describing student
knowledge and providing insight into how
mathematical solutions to tasks are built
by students
Researchers can gain insight into
students’ mathematical thinking
Can use interviews in their classrooms
to study how young children think
about and learn mathematics as well as
to assess the mathematical knowledge
of their students
The reasoning in problem-solving
situations of small groups of
students can also be made with
open-ended task-based
assessments
COMPONENT
A Carefully constructed task
like a key of the task-based
interview in mathematics
education
METHODOLOGY
-Record them with audio and/or
videotapes for later. The recordings,
accompanied by transcripts, observers’
notes, subjects’ work, or other related
metadata. Data from the interviews are
then coded, analyzed, and reported
according to the research questions
initially posed.
TECHNIQUES AND RESOURCES
Such as thinking aloud and openended prompting
USE
To investigate subjects’ existing and developing
mathematical knowledge and ways of reasoning,
how ideas are represented and elaborated, and how
connections are built to other ideas as they extend
their knowledge
TEACHING EXPERIMENT
A teaching experiment is an
experimental tool that derives
from Piaget’s clinical interview.
In this context, the interviewer
and interviewee’s actions are
interdependent
The interviewer intervenes by
experimenting with inputs that might
influence the organizing or reorganizing
of an individual’s knowledge
As in some task-based interviews, protocols
may be modified as observation of critical
moments suggests
